This is the strange part, we are running on a NetGear Gigabit router or 10/100(tryed both routers), i've tryed several different lan cables, network drivers for my onboard lan card, setup all our networks on mshome.
Here is the worst case scenario i've encountered. When we were playing battle field two i have another friend host, i joined in, so did everybody else, i kept loosing connection after a minute or two, so i figured my customized Nforce 3 (8.22 remix package off guru3d) might be causing it, so i switched back to 5.11's WHQL, same problem with those drivers. Then i figured it might be a problem with my onboard card(maybe the controller was damaged from ocing my cpu as in the pci bus lock was some how not working), tryed an older linksys 10/100 addin lan card, same exact problem, reset up my network on mshome just like everybody else, same problem. He cannot see files on my computer, he can see the folders but they are all empty when he goes in, yet everyone else can access them fine. Then he hosted a game, i still get disconnected, we finally figured out that i only get disconnected from a serve when HE joins the server, or he hosts the server, if i don't get disconnnected its so laggy i can't even play.
He refuses to admit its his computer causing the confict, even though i've tryed different drivers, different network cards, even full reformats!! i have no problem with online servers, down loads or anything else. Any ideas? he is running XP-64 bit, i can't because there are not stable NF3 drivers for it, and it really doesn't bring me any benefits. but when i did get 64bit to work with beta chipset drivers, it still had the same problem, but as i mentioned before, 64bit is too buggy with only beta chipset drivers for nf3 so i switched back.
